Answer: m∠G = 41°

Step-by-step explanation:

      Opposite angles of parallelograms are congruent. This means that m∠G = m∠E, so we can write an equation using the given information.

Given:

      m∠G = m∠E

Substitue:

      5x - 9 = 3x + 11

Add 9 to both sides of the equation:

      5x = 3x + 20

Subtract 3x from both sides of the equation:

      2x = 20

Divide both sides of the equation by 2:

      x = 10

      Then, we will substitute this value of x back into the expression for m∠G.

5x - 9 = 5(10) - 9 = 50 - 9 = 41°

The value of the polynomial equations are

f ( -10 ) = 20201

f ( 2 ) = 17

f ( 3 ) = 142

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the polynomial equation be represented as A

Now , the value of A is

f ( x ) = 2x⁴ + x² - 10x + 1   be equation (1)

Now , when the value of x = -10

f ( -10 ) = 2 ( -10 )⁴ + ( -10 )² - 10 ( -10 ) + 1

On simplifying , we get

The exponential function [tex]A = 3.2 \times \frac{1}{2}^{\frac{36}{8}}[/tex] determines the amοunt of substance after 36 years to be 0.2 grams.

The fοrmula for an exponential functiοn is [tex]f(x) = a^x[/tex], where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.

The amοunt of a radioactive substance left after a certain number of half-lives can be calculated using the expοnential equation formula -

[tex]A = A_0 \times \frac{1}{2}^{\frac{t}{T}}[/tex]

where -

A0 is the initial amοunt of the substance

A is the amοunt of the substance remaining after t years

T is the half-life οf the substance

In this case, the half-life is 8 years, sο T = 8.

We want tο know how much of the original 3.2 grams of the substance wοuld be left after 36 years, so t = 36.

We can plug these values intο the formula to get -

[tex]A = 3.2 \times \frac{1}{2}^{\frac{36}{8}}[/tex]

A ≈ 0.2 grams

Therefοre, after 36 years, only about 0.2 grams of the original 3.2 grams of the substance wοuld be left.

The equation that best mοdels this situation is -

[tex]A = 3.3 \times \frac{1}{2}^{\frac{t}{8}}[/tex]

where A represents the amοunt of the substance remaining after t years, in grams.

Therefοre, the equation is [tex]A = 3.2 \times \frac{1}{2}^{\frac{36}{8}}[/tex].

[tex]\textsf{2.} \quad\left(f -g \right)(x)=- x^4+x^2+2x-9[/tex]

Step-by-step explanation:

To calculate (f ⋅ g)(x), multiply function f(x) by function g(x) by distributing the parentheses:

[tex]\begin{aligned}\left(f \cdot g \right)(x)&=(x^2+2x-6)(x^4+3)\\&=x^2 \cdot x^4 +x^2 \cdot 3+2x \cdot x^4+2x \cdot 3 -6 \cdot x^4 -6 \cdot 3\\&=x^6+3x^2+2x^5+6x -6x^4 -18\\&=x^6+2x^5 -6x^4+3x^2+6x -18\\\end{aligned}[/tex]

To calculate (f - g)(x), subtract function g(x) from function f(x) by applying the distributive law -(a + b) = -a - b:

[tex]\begin{aligned}\left(f -g \right)(x)&=(x^2+2x-6) - (x^4+3)\\&=x^2+2x-6 - x^4-3\\&=- x^4+x^2+2x-6 -3\\&=- x^4+x^2+2x-9\end{aligned}[/tex]

Answer:

(4,9)

Step-by-step explanation:

The word "vertex" isn't clear here. I'm assuming the question is referring to finding the stationary (turning) point. This can be found by finding the derivative (dy/dx).

To find the derivative we use the following formula:

[tex]y = ax^{n}\\ \frac{dy}{dx} = nax^{n-1}[/tex]

What this means is that for each term of the equation, we multiply by the current power and then reduce the power by 1. In the case of the question's equation, this will be done like this:

[tex]y = 3x^{2} - 24x + 57\\\frac{dy}{dx} = 6x - 24[/tex]

Now we can use this to find the stationary point, as stationary points are where the derivative (dy/dx) = 0:

6x - 24 = 0

6x = 24

x = 4

Through this we have found the x-coordinate of the stationary point, however we still need to find the y coordinate. This is done by substituting our x value back into the original equation (not the derivative):

y = 3(4)² - 24(4) + 57

y = 9

Therefore, the coordinates of the stationary point are (4,9)

The trade discount is $15.75.

A trade discount is a regular reduction from a product's regular, established price. The use of trade discounts allows a company to adjust the final price based on the volume or status of each customer.

It is important to note that trade discounts are not the same as early-payment discounts. (Early-payment discounts of 1% or 2% are typically recorded by the seller in an account such as Sales Discounts and by the buyer in an account such as Purchase Discounts using the periodic inventory method.) Neither the seller nor the buyer keeps a separate account for trade discounts.

We must first determine the product's list price in order to determine the trade discount.

List price: $75 plus $3.75 equals $78.75

As the trade discount rate is 20%, the following discount is offered:

Discount = 0.2 times List price = 0.2 times $78.75 = $15.75

Answer:

The strip pattern has a vertical axis of symmetry, so a reflection across a vertical line will map the strip pattern onto itself. Therefore, the correct answer is "a reflection across a vertical line."

Step-by-step explanation:

The decay of Element X can be modeled by the equation:

N = N0 * (1/2)^(t/t1/2)

where N is the amount of Element X remaining after time t, N0 is the initial amount of Element X, t1/2 is the half-life of Element X, and ^(t/t1/2) denotes exponentiation with base 1/2.

We know that the initial amount of Element X is 470 grams, the half-life is 8 minutes, and we want to find the time it takes for Element X to decay to 10 grams. Let t be the time in minutes.

Then, we can set up the following equation:

10 = 470 * (1/2)^(t/8)

Dividing both sides by 470, we get:

(1/47) = (1/2)^(t/8)

Taking the natural logarithm of both sides, we get:

ln(1/47) = (t/8) * ln(1/2)

Solving for t, we get:

t = -8 * ln(47)/ln(2)

t ≈ 59.3

Therefore, it would take about 59.3 minutes, to the nearest tenth of a minute, for Element X to decay to 10 grams.

We're given the angle measure to be 46 for No. 8. The length of 1 leg is x and the hypotenuse is 28.

We can use cosine to solve this. Since cosine is adjacent over hypotenuse, we can do cos(46) = x/28. Cross multiply to get cos(46)*28 = x. That solves to be 19.5

Using this principle allows us to solve the other ones. I'll let you figure them out.

TLDR: We can use the definition of trig functions to plug in what we know and place variables where we don't have enough information to find the length of a side.
